| The gap between performance and feed intake in early lactating dairy cows often leads to metabolic imbalance which is connected to udder inflammation (UI). A study with 72 dairy cows calving from November 2010 to March 2011 on 10 Swiss and German farms was conducted to test the effect of a herbal feed additive (HFA) containing mainly Urtica dioica L. (herba), Silybum marianum (L.) Gaert. (fructus), Artemisia absinthium L. (herba) and Achillea millefolium L. (herba). Cows were stratified (farm and milk yield) randomised divided into three groups. From 14 days prior predicted calving to the end of the following lactation cows received daily 100 g pellets containing A: 100% HFA, B: 50% HFA and 50% alfalfa and C: 100% alfalfa (placebo). Two or three cows per... |

| Aim of this study was to test the influence of feeding strategy on faecal particle size distribution as indicator of fibre digestion under on-farm conditions. Seventy-six cows from 11 farms, located in Switzerland and southern Germany were included. Cows were monitored up to eight times during one full lactation. All valid individual test days resulted in a total of 347 datasets. Milk yield and composition were recorded. Diet composition was described in a binary yes/noindication for the presence or non-presence of different roughage components (fresh grass, grass silage, hay, maize silage and straw) and the exact amount of concentrates. Faecal samples were taken at each test day and sieved with a set of four wire‐mesh screens with pore sizes of 4mm, 2mm,... |

| On 25 Swiss and German organic dairy farms all fresh cows (a total of 283 cows between 5 and 50 days in milk) were tested weekly for blood- -hydroxybutyrate (BBHB), 121 exceeded the threshold of 1.0 mmol/l BBHB. A total of 84 cows were randomly assigned to three treatments which were given daily, diluted in 700ml fluid divided to two oral administrations for 4 days: placebo (PL), 240g sodium propionate per day (SP) and 240g sodium propionate combined with an extract of seven herbs (27g drug equivalent). Milk acetone (MAC) and BBHB were observed during the administration period and thereafter, in total for two weeks. A reduction of ketone bodies was measured in all three treatment groups. No significant differences between SP and PL arose regarding the... |
